 =====Prerequisites=====
 Use the Kiosk howto to install a R/O Kiosk. Magic Mirror software runs from the home directory of the user and can only be R/W. I used a USB SSD connected to the USB3 port of the Raspberry Pie 4.

 Rotate the graphical interface does not seem to work on a Pi 4. As you can see we are using xrandr to rotate. Rotation of the console must be disabled and the GL driver must be enabled.
 Use raspi-config to change to GL driver: 7 Advanced Options -> A8 GL driver -> G2 GL (Fake KMS)
+==== Console ====
 Then change /boot/config.txt to remove rotate screen

+The console messages will be in unrotated format which is ugly. Disable all console logging:

+===== Install=====
+We are going to use the recommended manual way:
+====Install packages====
+We must be the pi user
+<code>
+curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
+</code>
+<code>
+sudo apt-get -y install git nodejs libnss3 libxtst-dev libxss-dev
+</code>
+==== Install Magic Mirror ====
+<code>
+cd ~
+git clone https://github.com/MichMich/MagicMirror
+cd MagicMirror/
+npm install
+npm audit fix
+npm install electron@6.0.12
+</code>
+Now copy the sample config in place:
+<code>
+cd ~/MagicMirror/config
+cp config.js.sample config.js
+</code>
+==== Autostart Magic Mirror on boot ====
+Install PM2 process manager
+<code>
+sudo npm install -g pm2
+pm2 startup
+</code>
+The startup command creates a commandline we need to execute to create a systemd service. Execute it. In our case:
+<code>
+sudo env PATH=$PATH:/usr/bin /usr/lib/node_modules/pm2/bin/pm2 startup systemd -u pi --hp /home/pi
+</code>
+Create a little script in homedir of pi with name mm.sh
+<code - /home/pi/mm.sh>
+cd ~/MagicMirror
+DISPLAY=:0 npm start
+</code>
+<code>
+chmod +x mm.sh
+</code>
+<code>
+bash -c "$(curl -sL https://raw.githubusercontent.com/sdetweil/MagicMirror_scripts/master/fixuppm2.sh)"
+</code>
+Reboot and enjoy
